Hamilton Khaki Field Titanium Auto 42mm

When the Khaki Field Titanium Automatic arrived in 2020 it came as two 42 mm references, and H70545550 is the uncoated one, still part of Hamilton's current collection. Hamilton's page gives no grade, but Monochrome identifies the case as Grade 2 titanium, brushed all over, with TITANIUM engraved on the left flank. The dial is dark grey and black, with a 24-hour scale in the grey centre and large Arabic hours on a black, spiral-textured ring around it, with green Super-LumiNova on the syringe hands, and there is no date. The H-10 inside is Hamilton's reworked ETA calibre, slowed to 3 Hz to stretch the reserve to 80 hours, and it shows through a sapphire caseback. Hamilton gives the thickness as 11.45 mm, and Gnomon Watches measured 52 mm from lug to lug and 64 g on the leather strap, which closes with a titanium H-shaped buckle. It lists at $1,195.
